India's UPI system processed 21.7 billion transactions in January 2026 alone. That's more digital payments in a single month than most countries process in a year. And yet, roughly one in four Indian ecommerce orders still ships cash on delivery. So why do customers choose COD when a digital wallet is sitting right there on their phone?

Southeast Asia tells the same story. COD dropped from 52% of ecommerce payments in 2019 to 31% in Q1 2026 — but it hasn't disappeared. Even in Saudi Arabia, where 79% of retail transactions are now cashless, COD orders keep arriving. The pattern is clear: digital payments are winning, but a stubborn segment of buyers keeps choosing cash. If you're a COD merchant trying to shift your payment mix toward prepaid, understanding why matters more than understanding how.

It's Not About Trust Anymore (For Most Buyers)

The default explanation for COD preference has always been "customers don't trust online payments." That was true in 2016. It's less true now.

Most COD customers in 2026 have a digital wallet on their phone. They use UPI to split dinner bills, pay for ride-shares, and recharge their mobile plans. They trust digital payments for dozens of daily transactions. They just don't trust your store with a prepaid order — and those are two different problems.

The distinction matters because if you think the barrier is payment infrastructure, you'll wait for the market to solve it. If you recognize the barrier is store-level confidence, you can actually fix it.

Why Do Customers Choose COD Over Prepaid? Product Uncertainty

When a customer picks COD, they're often buying an insurance policy against disappointment. They want to open the box, check the product, and confirm it matches the photos before money leaves their hands.

This is especially true for:

First-time buyers who've never ordered from your store before
Fashion and apparel where size, color, and fabric feel can't be judged from a screen
High-ticket items where the financial risk of a bad product feels real
Stores with limited reviews or social proof — no evidence that other buyers were happy

The fix isn't removing COD. It's reducing product uncertainty. Detailed size guides, unboxing videos from real customers, a clear return policy displayed before checkout — these all chip away at the reason COD felt safer in the first place.

Household Budgeting Is a Hidden Driver

In many emerging markets, household finances don't work the way most payment guides assume. Money doesn't sit in a single bank account waiting to be spent. It's distributed across family members, allocated to specific purposes, and often managed in cash.

A customer might order a product on Monday knowing they'll have the cash by Thursday when the courier arrives. Their digital wallet might have a balance, but that balance is earmarked for groceries or school fees. COD lets them buy now and pay with different money later — effectively a zero-interest credit line that doesn't require a credit card or BNPL approval.

This is why COD persists even among digitally literate shoppers. It's not that they can't pay digitally. It's that COD fits their cash flow better than an immediate debit from their account.

Shared Devices Create a Payment Barrier You Can't See

In South Asia and parts of Southeast Asia, shared phone usage is common. A teenager orders on a parent's phone. A wife orders on a husband's device. A younger sibling uses an older sibling's saved login.

When the phone belongs to someone else, entering payment credentials feels uncomfortable — even if the buyer has their own digital wallet. They'd need to log in to their UPI app, authenticate, and complete the transaction on a device that isn't theirs. COD sidesteps all of that. The order goes through with just a name, phone number, and address.

You'll never see this in your analytics. There's no "shared device" flag in Shopify. But if you sell in markets where household device sharing is common, a meaningful percentage of your COD orders come from this exact friction.

Delivery Uncertainty Makes Prepaid Feel Risky

In markets where courier reliability is inconsistent, paying before delivery feels like a gamble. The package might arrive in two days or two weeks. It might arrive damaged. It might not arrive at all.

COD return rates run 12-15% compared to 3-5% for prepaid orders. That gap exists partly because COD attracts less committed buyers — but also because COD gives customers a safety valve. If the package arrives late, damaged, or wrong, they simply refuse it. No refund process, no support ticket, no waiting three weeks to get their money back.

For merchants, this is expensive. But for customers, it's rational. Until your store proves it delivers reliably, prepaid carries real risk from the buyer's perspective.

How to Design Prepaid Incentives That Actually Work

Most merchants try to shift COD buyers to prepaid with a flat discount: "Pay online and save 5%." It works on some buyers. But if you understand the reasons above, you can design smarter incentives that address the actual objection.

For product uncertainty: Offer a no-questions-asked return policy for prepaid orders. The guarantee removes the reason they wanted COD inspection rights.
For budgeting concerns: Offer a partial payment option — a small deposit at checkout with the rest on delivery. This gives buyers the commitment flexibility of COD with a lower RTO risk for you. EasySell's partial payment feature lets you set deposit percentages directly on the order form without any code.
For delivery uncertainty: Add real-time order tracking and estimated delivery dates. When customers know exactly when their order arrives, prepaid feels less like a leap of faith.
For shared device friction: Keep your COD form simple and fast. If this segment can't easily pay digitally, at least make their COD experience frictionless — then focus your prepaid conversion efforts on buyers who do control their own device.

The key insight: a single prepaid discount treats all COD buyers as one group. They're not. A first-time buyer worried about product quality needs a different nudge than a repeat customer who picks COD because it fits their pay cycle.

Stop Fighting COD — Start Segmenting It

The merchants making the fastest progress on payment mix aren't the ones who removed COD or penalized it with fees. They're the ones who figured out which COD buyers can be converted and which ones are choosing cash for reasons a discount won't fix.

Your repeat buyers who've ordered three times and still pick COD? They're budgeting buyers. A deposit option or BNPL integration will move them faster than a 5% discount.

Your first-time buyers from social ads? They're trust-gap buyers. Better product pages, reviews, and a visible return policy will do more than any payment incentive.

Your buyers in areas with poor courier coverage? They're delivery-uncertainty buyers. Fix the logistics first. The payment method follows.

COD isn't one problem. It's four or five different buyer behaviors hiding behind the same payment method. The merchants who segment those behaviors — and design different responses for each — are the ones moving their prepaid share 5-10 points per quarter instead of fighting the same flat-discount battle every month.
